Abstract
The invention discloses a polypropylene pipe for an underground coal mine, comprising the following components in parts by weight: 75-80 parts of polypropylene, 4-15 parts of a fire retardant, 10-15 parts of an antistatic agent, 3-5 parts of a biocompatible material, 5-10 parts of an anti-impact modifier, 0.5-1 part of an antioxidant and 0.5-1 part of a dispersing agent. The polypropylene pipe for the underground coal mine has the beneficial effect that the characteristics of polypropylene, including high tensile strength, good toughness, resistance to action of various organic solvent, good high temperature tolerance and the like are well utilized, and the polypropylene pipe for the underground coal mine has good antistatic and flame-resistant performance, and can satisfy the usage in coal mine underground 3.2MPa pipeline systems. While the flame-resistant and antistatic properties of the polypropylene material are improved, the toughness and strength of the material are not reduced.
Description
Technical field
The present invention relates to underground mine use tubing field, particularly relate to and adopt polypropylene (PP) the dual anti-polypropylene pipes for mining made for underground coal mine water supply and sewage, pressure wind, gas drainage and whitewashing etc.
Background technology
In early days, the various pipeline of underground mine use is mainly based on steel pipe, Glass Steel Tube, pvc pipe etc., but because Glass Steel Tube surface easily comes off, to human health, pvc pipe poor toughness, easily break, the problems such as poor stability, not recoverable were classified as the product of explicit order restriction in 2005 by national Work Safety Supervision Bureau, and steel pipe is also eliminated gradually due to reasons such as its heavy, perishable, easy generation electrical spark.In recent years by underground mine use polyethylene (PE) pipeline extensively promoted and polyethylene (PE) Steel Skeleton pipe, to some extent solve the deficiency of the said products, but because polyethylene pipe exists intensity difference (maximum pressure-bearing is 1.6MPa), easily sagging, the shortcomings such as heat resisting temperature is low, use cost is higher on the one hand,, heat resisting temperature higher in requirement of strength requires that higher occasion cannot meet service requirements on the other hand, particularly along with the rise of the PE prices of raw and semifnished materials, it does not have advantage in cost performance; And polyethylene (PE) is although Steel Skeleton pipe rigidity is better, the shortcomings such as solve the problem of poly-second pipeline poor rigidity to a certain extent, it exists easy layering, sealing for tubing joints difference, also cannot use at underground coal mine well.At present existing research report apply at underground coal mine about the dual anti-pipe of ultrahigh molecular weight polyethylene(UHMWPE), but due to ultrahigh molecular weight polyethylene(UHMWPE) difficulty of processing greatly, expensive, cannot promote at all.
Summary of the invention
In order to the polypropylene pipe solving prior art formula cannot meet underground coal mine Code in Hazardous Special Locations needs static resistance and flame retardant resistance, the invention provides a kind of polypropylene pipes for mining, it has good static resistance and flame retardant resistance, can be applied in underground coal mine.
In order to realize foregoing invention object, the technical solution used in the present invention is:
A kind of Polypropylene pipe for underground coal mine, comprises following parts by weight of component:
Polypropylene 75 ~ 80 parts;
Fire retardant 4 ~ 15 parts;
10 ~ 15 parts, static inhibitor;
Compatibility material 3 ~ 5 parts;
Anti-impact modifier 5 ~ 10 parts;
0.5 ~ 1 part, oxidation inhibitor;
Dispersion agent 0.5 ~ 1 part.
Wherein, described fire retardant is one or both combinations in inorganic anti-flaming material and organic fire-resisting material.
Wherein, described fire retardant is the compound of red phosphorus combustion inhibitor, antimonous oxide, TDE and decabromodiphynly oxide, counts by weight:
Red phosphorus combustion inhibitor 40 ~ 60 parts
Antimonous oxide 20 ~ 30 parts;
TDE 10 ~ 20 parts;
Decabromodiphynly oxide 10 ~ 20 parts.
Wherein, described compatibility material is one or both combination or the three kinds of combinations in polypropylene grafted vinylformic acid, polypropylene grafted maleic anhydride or ethylene-vinyl acetate copolymer grafted maleic anhydride.
Beneficial effect of the present invention is, the features such as Polypropylene pipe for underground coal mine road of the present invention both make use of that the distinctive tensile strength of polypropylene is large well, good toughness, the effect of resistant to many organic solvent, high thermal resistance are good, make it have again good anti-electrostatic fire retardant performance, the use of underground coal mine 3.2MPa tubing system can be met.While the flame retardant resistance improving polypropylene material and static resistance, do not reduce again toughness and the intensity of material.
Embodiment
By describing technology contents of the present invention, structural attitude in detail, being realized object and effect, be explained in detail below in conjunction with embodiment.
fire retardant: the present invention adopts fire retardant can be inorganic anti-flaming material or organic fire-resisting material.Inorganic anti-flaming material has the metal oxides etc. such as aluminium, magnesium, antimony, molybdenum, zinc.Organic fire-resisting has phosphoric acid salt, borate, vitriol etc. to have Halogen fat hydrocarbon and aromatic hydrocarbon.Preferably combination is red phosphorus combustion inhibitor, the compound of antimonous oxide, TDE and decabromodiphynly oxide, counts by weight:
Red phosphorus combustion inhibitor 40 ~ 60 parts;
Antimonous oxide 20 ~ 30 parts;
TDE 10 ~ 20 parts;
Decabromodiphynly oxide 10 ~ 20 parts.
static inhibitor: static inhibitor English name is Antistatic agent, is called for short ASA.Because the volume specific resistance of polymkeric substance is generally up to 1010 ~ 1020 Ω cm, easy savings electrostatic and causing danger, and static inhibitor polyphyly tensio-active agent, can make frosting affinity moisture, ionogenic surfactant also has electric action, and electrostatic thus can be made to leak in time.The static inhibitor that invention adopts is that non-ionic type resists quiet dose.
Compatibility material: i.e. compatilizer, the present invention adopts Macromolecular Compatibilizer as compatibility material, is specially one or both combination or three kinds of combinations in polypropylene grafted vinylformic acid, polypropylene grafted maleic anhydride or ethylene-vinyl acetate copolymer grafted maleic anhydride.
anti-impact modifier: refer to one or more combinations in polyolefin elastomer grafted maleic anhydride, polypropylene grafted maleic anhydride, Chlorinated Polypropylene III or thermoplastic elastomer.
The preparation method of Polypropylene pipe for underground coal mine of the present invention comprises: by be correlated with in following examples constituent materials mixing, adopt extrude, mold pressing or injection system process above-mentioned materials mixing; To describedly extruding, the tubing that obtains of mold pressing or injection system carries out cooling forming.
Contriver draws through test of long duration, while the flame retardant resistance improving polypropylene material and static resistance, does not reduce again toughness and the intensity of material, and ability is acquired can better Polypropylene pipe for underground coal mine material.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
